Over the past 30 years the end use for linen has changed dramatically. Approximately 70% of linen production in the 1990s was for apparel textiles, whereas in the 1970s only about 5% was used for fashion fabrics.

Linen uses range across bed and bath fabrics (tablecloths, bath towels, dish towels, bed sheets); home and commercial furnishing items ; apparel items; and industrial products. It was once the preferred yarn for handsewing the uppers of moccasin-style shoes (loafers), but has been replaced by synthetics.

A linen handkerchief, pressed and folded to display the corners, was a standard decoration of a well-dressed man's suit during most of the first part of the 20th century.

Currently researchers are working on a cotton/flax blend to create new yarns which will improve the feel of denim during hot and humid weather.

Linen fabric is one of the preferred traditional supports for oil painting. In the United States cotton is popularly used instead, as linen is many times more expensive there, restricting its use to professional painters. In Europe, however, linen is usually the only fabric support available in art shops; in the UK both are freely available with cotton being cheaper. Linen is preferred to cotton for its strength, durability and archivalintegrity.

Linen is also used extensively by artisan bakers. Known as a couche, the flax cloth is used to hold the dough into shape while in the final rise, just before baking. The couche is heavily dusted with flour which is rubbed into the pores of the fabric. Then the shaped dough is placed on the couche. The floured couche makes a "non stick" surface to hold the dough. Then ridges are formed in the couche to keep the dough from spreading.

In the past, linen was also used for books (the only surviving example of which is the Liber Linteus). Due to its strength, in the Middle Ages linen was used for shields, gambesons, and bowstrings; in classical antiquity it was used to make a type of body armour, referred to as a linothorax.

Because of its strength when wet, Irish linen is a very popular wrap of pool/billiard cues, due to its absorption of sweat from hands. Paper made of linen can be very strong and crisp, which is why the United States and many other countries print their currency on paper made from 25% linen and 75% cotton.
